Kasarwadi Phase II Wastewater Treatment Plant, Pimpri-Chinchwad, Maharashtra

Kasarwadi Phase II is a wastewater treatment plant located in the Kasarwadi area of Pimpri-Chinchwad, a major industrial and residential city in Maharashtra, India. The plant serves a population of about 267,000, placing it among the larger treatment facilities in the region. It is part of the municipal infrastructure managed by the Pimpri-Chinchwad Municipal Corporation. As a large-scale treatment facility in India, Kasarwadi Phase II operates under the national environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. The Central Pollution Control Board (CPCB) and Maharashtra Pollution Control Board (MPCB) set discharge standards for treated wastewater. For plants of this scale, secondary treatment is typically required, and compliance with effluent standards is monitored through consent orders. The treated effluent from Kasarwadi Phase II is likely discharged into local water bodies that eventually drain into the Mula-Mutha river system, which flows through Pune and joins the Bhima River, a tributary of the Krishna River. The Krishna River basin supports diverse aquatic life and is crucial for irrigation and drinking water in the region. The plant's operation helps reduce pollution loads in these rivers, protecting downstream ecosystems and communities.

The plant's treated effluent enters the Mula-Mutha river system, which flows through Pune and joins the Bhima River, a major tributary of the Krishna River. The Krishna River basin is ecologically significant, supporting diverse aquatic species and providing water for agriculture and domestic use. The plant helps mitigate pollution in this important watershed, reducing the impact of urban and industrial wastewater on downstream environments.
